I've uploaded about 100 new fabric texture images on my TXR - FABRIC page. They are all seamless, 2048X2048 and ready for tiling.
New fabric types include Leather, Rayon, Metal Linens, Dyed Acrylics and various weaves.
They might be useful for clothes for characters, furniture coverings, carpets, or anything else you can think of.
I hope some of them are useful!
